Quentin had a cortisone injection in his left — or good — knee Tuesday to relieve the irritation caused by the slide. He didn’t play Tuesday night and was out of the starting lineup again Wednesday. And Black stopped short of saying Quentin would be available as a pinch-hitter.

Black said he expects Quentin to be back in the lineup this weekend in Arizona. And Quentin likely will be available as the designated hitter Monday and Tuesday in Seattle.

The left knee is not the knee that has troubled Quentin since the spring of 2012 when he had the first of two surgeries on his right knee.

Quentin also appeared to hurt his left shoulder on the slide, although Black said Wednesday the shoulder was OK.

Quentin’s knee was not the only injury-related news of the day involving the Padres. And the two other items were positive.

Maybin will join Triple-A Tucson on Friday night and is expected to spend at least 10 days with the T-Padres. Black has said Maybin, who has been out since April 17 with an inflammation in his right wrist inflammation, needs at least 30 at-bats.

“I’m really excited to be back in the mix,” Maybin said. “The wrist has felt good when I’ve been taking batting practice. I think we could finally be on top of it now that we know what it is.”

Maybin has said there is a possibility of having surgery after the season.

Forsythe will spend time at extended spring training at the Padres’ temporary base at Surprise, Ariz., before reporting to Tucson.

He has been sidelined since early in spring training with plantar fasciitis in his right foot, although he did make several cameo spring training appearances in hopes of being ready by Opening Day.

Forsythe ran the bases Wednesday. “I’m going to extended spring training to get my feet under me and get some extra hitting in before going to Tucson,” said Forsythe.
